To all whom it may conccrmj Be-it known that I, JULIANYZRVBRANDONQ Jr. a citizenofthe llnited States,;and a IQSlClSIlt} of the city and county of San Francisco, State of California; have made a. new and useful nvent onto wit, Gondensers for Radiators; and Ido, hereby declare the following to bee fulhicleanconoise, and exactdescriptionofthegsanie 1 V The invention relates"particularlyto con densers. torthe f radiators of'an internal combustion motor and more particularly for radiators onvmotor vehicles. 7 Among the ob ects-of the inventnmv are to conserve the waterfsupply oithe radiator by avoiding-the wastagethereof by evaporation, ejection through the overflow pipe due to expansion by heat, and by gravity. when. the vehicle descends steep inclines; Other, obj eots. and advantages will appear;

as this description progresses.

In this specification and the annexed drawings, the invention is illustrated in the form consideredcto. be thebest but it is to g be understood that the. invention is not limited to .suchfornn'because it may be ein-' bodied in other forms, and it is also tobe understood that inr andby the. claims fol g gasket 12 to seal the center opening in the lowing the descriptionit is desired-tocover the invention rill whatever form; t may? be embodied. r

' the water becoming;expanded by the absorption got heat would burst the radiator unless .ov-erflow means were provided.

When this invention is applied toa radiator, it is necessary to plug or remove the usual overflow pipe to compel any overflow to pass through the device.

In detail. the construction of the invenfcontinuous length or tubing havingits lower end ,thread'ed as at 4 and passer:

Continulng upward the tubing is bent pression'coupling' 7 joining it to'the over fiolw pipe 8 carried down the radiator 01 disposed 1110,113 suitable or convenient man ,Iti'on illustrated in the drawings includes a ner to carry the overflow from the radiator; v I

' To prevent vibration ofthe coils 5 T interpose the non-heat conducting base 9, pretierably cylindrical inio'rmand hollowed at thebase toprovide the concentric edges as v at lOtoj rest on top of the cap;1. The concave bottom accommodates itself to the convex top oi? the cap 1. The lock nut 11 threaded onfthe tube'4 bears against the notched at their outer edges to reecive the coils 5 and" separate them the desired dis ,tance to prevent conduction oiheat, pre vent vibration {and interspace the coils to permit tree circulation i of air thereabout,

The flat portion tthe support is provided. with; the central opening,flz .s at 15,,so that i the support presents the minimum amount of resistance to the circulation of air about the coils. The terminal coil is attached .to .the top of the support member by the'strap lined thereto and engaging the coil. :When it s des red .to reinove the cap I vto refill the radiator, tl'ie coupling '73s opened,

separating'the tubes 6 and 8, and permit- The coils 5 are wound about. a suitable mandrel to, give them the desired shape,

jwhich preferablyelliptical asillustrated in jl q The,,e Xte nsion i is then passed down through the central opening in the base 9 the'fiattened port1ons'13--14- lying plied to the radiator of" an automobile. the cold radrator 1s filled with cold water to lengthwise of the'coil. The base 9 is then given av quarter turn, which causes the notches in the supports 13-14 to engage their respective coils with sullicient tension to prevent'vibration of the coils and hold them in-separated relation, as described. The strap 16 is then fastened in place and the condenser is "fully assembled, giving a very simple, compact, effective and'ornamental construction. The base and the sup ports 131 lmay be formed integrally or any suitable composition such as vulcanized C011] OllllClS COllliZlllllllP it lar e )ercenta e of asbestos or other heat nonconducting material. Thecoils 5 are preferably formed of seamless drawn copper tubing nickled, enameled r finished to suit the taste of the user.

This invention operates substantially as follows: li'esuming the condenser to be ap- It full capacity, the first result following the operation of the motor is to expand the water by absorbed heat from the motor, the

surplus being ejected through the pipe 1, coils 5, and the waste pipe 8, relieving the radia tor from the internal pressure or expansion of the water therein. Should the water in the radiator rise to the boiling point, the steam or vapor enerated would eject a certain amount of the waterlcont'ained within intotheradiator in the form of water. This effect continues during the normal operation of the veh cle. W hen an incline 1S encountered the water level may be lowered in the radiator because of the body of water-set-' t'ling back into the water jackets and other spaces surrounding themotor, the usual quantity continunig to circulate by thermosiphon circulation or the operation of a forcepump when the same is' installed in the piston. The receding of the water from the rad ator will cause a momentary suction through the coils5, drawing into the radiator any water or vapor that may be contained therein. When adecline is encountered by the vehicle the waterimmediately and sometimes violently rushes forward into the top of the radiator, gushing out through the usual'overfiow pipesflf they are present, resulting in a considerable loss of water.

'Where this invention is installed, the usual overflow pipes are plugged or absent. 7

Having-thus described my 1nvent1o11, What.

I claim and desire to secure by Letters Patent is:

1. Incombination with the removable cap of a radiator, a tubular helix coil having its inlet end fixed in said cap and open to the interior of the radiator and extending exteriorly thereabove and having a descending overflow tube terminating below the top of said radiator, and a base fixed to said cap having notched supports thereon engaging the coils of saidhelix.

2. In combination with the removable cap of a radiator, a tubular helix coil having its inlet end fixed in said cap and open to the interior of the radiator and extending exteriorly thereabove and having a descending overflow tube terminating below the top of said radiator, and a base fixed to said cap having notched supports thereon engaging the coils of said helix; and a strap fixed to said supports and engaging said overflow tube.

3. In combination with the removable cap of a radiator, a tubular helix coil having its inlet end fixed in said cap and open to the interior of the radiator and extending exteriorly thereabove and having a descending overflow tube terminating below the top of said radiator; and a base encircling said in let end o1 said coil and having a flattened body with a lateral opening therethrough, and notched edges engaging the coils of said helix.

1-. In combination with the removable cap of a radiator, a tubular helix coil having its inlet end fixed in said cap and open to the interior of the radiator and extending exteriorly thereabove and having adescending overflow tube terminating below the top of said radiator; and a non-heat-conducting Jase encircling said inlet end of said coil and having a flattened body with a lateral opening therethrough, and notched edges engaging the coils of said helix.

5. In combination with the removable cap of a radiator, a tubular helix coil having its inlet end threaded and extending through said cap and open to the interior of said radiator, and extending exteriorly thereabove; a base engaging said'inlet tube above threaded on said inlet and bearing against said cap; said base having a support thereon said cap and drawn'thereagainst by a nut engaging and separating the coils of said helix;
